Through the process of theoretical analysis, data tracking analysis, model simulation field experiment and so on, it has established the ef-fective and reliable control strategies and realized the urban water supply automation, informatization and intelligentization. DCS hardware system has multi-level redundancy configuration to ensure long- term reliable operation of system. The system software breaks through single station control mode, cooperates with each unit and has achieved the integrated management. The effective integration of process control and communication technology has achieved meticulous evaluation of operation state. The design for the network topological structure of DCS has followed the basic real-time, reliable, advanced, open, and easy principles; it has integrated management and control, dynamic production scheduling, advanced process control and optimization, and fault processing characteristics such as expert system. By DCS application in Shanghai Yuepu Water Plant, the intelligent control system of water plant based on DCS adapts to actual demand for waterworks, meets the development direction to reduce costs, improves management, and perfects the service. It has provided reliable technical support that ensures stable operation, improves water quality, reduces energy consumption, and realizes the modernization management for the water plant. At the same time, it constructs a part of the smart city.
